If they do serve the Heterodyne they’re honorary Mechanicsburgers already.
Not sure I believe Tarvek’s actually the most dangerous person in his family, though. I haven’t seen much evidence of it.
Maybe Higgs doesn’t mean Tarvek is dangerous in a strictly objective sense. Maybe he means Tarvek is dangerous because of how much damage he could do to the Heterodyne. I think Tarvek may well be the first in his family to actually be this close to a Heterodyne since… oh, since old Prince Vadim was friends with the Good Heterodyne?
I mean, even the last Heterodyne’s consort wasn’t allowed to know about the secret general (given that Lu being in Agatha’s head is the whole reason Agatha isn’t allowed to know about him), and Tarvek figured it out by himself. And now is allowed to live despite that knowledge.
Ooh. Excellent point. Sturmvariouses = trouble. Sturnvariouses the Heterodyne likes = much more trouble.
There’s also the similar but inequivalent power of love read: “Actually giving a damn about something means your schemes might actually go somewhere because you have a real reason.”
Love overcomes all forms of executive dysfunction
